Not all book video will be accepted by those sites even if the video is non-fiction, author interview or a DIY book. The secret to getting your video accepted is to offer something of value, something that will teach the viewer how to do something from beginning to end. It can’t be suggestions, opinions or even a video on what your DIY book is about. It needs to be a full DIY session that gives the viewer a lesson.
If you have a book that you think would be perfect for this type of site, ask yourself what your book is teaching someone. If you can break it down into several things, choose one representative lesson and give it away in order to sell the idea of the book. Give a beginning and end to the lesson in which someone actually learns how to do something.
Book videos can easily present as a commercial if the selling points of the book are greater than the entertainment value of the video. Give away a lesson. That’s the price of getting onto one of these sites.
